Preheat oven to 425. Lay a sheet of tinfoil over a baking sheet. Place defrosted chicken wings on a baking sheet. Put in heated oven for 15-20mins. This gives them a crust so they won't fall apart in crock pot.
Dump wings and excess juices in crock pot and add undrained crushed pineapple and terryaki sauce. Cook on high for 3-4 hours on high or until done. Remove from pot and top with sesame seeds. I like to serve this over white rice too.
